'I'his invention relates to the manufacture of manifolding material, and particularly of tabbed material whereby finger tabs and cutouts are provided in succeeding sheets of transfer material interposed between the record strips to facilitate the separation of detached portions of the record and transfer material.

The present invention is a further development and improvement in the process of manufacture of the tabbed manifolding material shown and described in applicants co-pending applications for Letters Patent Serial No. 435,213 filed Mar. 12, 1930; Serial No. 437,655 led Mar. 21, 1930; Serial No. 444,724, flled Apr. 16, 1930, and Serial No. 551,724 filed July 18, 1931.

While for illustrative purposes the present invention has been shown applied only `to finger tabs of semi-circular form, it is to be understood that the present invention and method of production are applicable to finger tabs of various shapes and proportions such as shown in the above identified pending applications for patents.

It has been found in the manufacture of tabbed manifolding material wherein the material is scored or weakened on transverse lines at spaced intervals for Asubsequent sub-division into succeeding sheets, that the continuation of the score lines or weakening lines across the area of the tabs results in the tabs being accidentally torn off. It is also found that because of the weakened line across the base of the tab, the tab is quite likely to become displaced or reversed intermediate the record sheets thus leaving a vacancy in one sheet and doubling the thickness of the transfer material commensurate with the area of the tab in the adjacent sheet which also, due to reversal of the tab, prevents transfer over such area.

The object of the present invention is to overcome the difficulty of manufacture heretofore experienced, and to provide a method of providing' tabbed stationery in which the tab will be of "maximum strength and unweakened or unaffected by the scoring of the material, and wherein the tab will be caused to maintain its normal relation in the plane of the transfer strip during the feeding and writing operation.

A further object of the invention is to provide an improved method of manufacture which will be economical, and which will not involve difflculties of manufacturing operation nor the necessity for special equipment other than that heretofore employed in the manufacture of similar material. Y

With the above primary and 4other incidental objects in view as "will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and vset 5 forth in the claims. Referring to the accompanying drawing, Fig. 1 is a perspective view of a portion of a strip of transfer material in which thespaced finger tabs and cutouts have been formed preparatory to l0 the transverse scoring or perforation upon spaced division lines. Fig. 2 illustrates the reversely folded finger tab, the fold lines of which are in slightly spaced relation with the transverse division lines of scoring or perforation and hence not 15 intersected thereby. Fig.' "3 is a` perspective view o'f a packet of superfolded manifolding material `including interposed tabbed transfer strips manufactured in accordance with the present method. Fig. 4 is a detail view of a portion of the strip 20 of transfer material removed from the packet and illustrating the effect of refolding of the finger tabs simultaneously with the folding of the strip upon the transverse division lines. Fig. 5 is a perspective view illustrative of the method 25 of detaching packets of superposed leaves from the strips of manifolding material. Fig. 6 is a similar view illustrating the manner of separatlng the detached -leaves of record and transfer material.

Like parts are indicated by similar characters of reference throughout the several views.

Briefly stated the present method of production consists in initially cutting the strip of transfer material at spaced intervals to form the requisite finger tabs and corresponding cutouts and folding the tongue or tab thus formed reversely onto the strip of material, and thereafter transversely scoring or perforating the strip of transfer material in slightly offset relation with the fold line 40 of thetab or tongue so that the latter is not intersected Vor weakened and after returning the preliminarily` folded tab to its normal position within the cutout, the strip is reversely folded y into zig-zag formation upon succeeding weakened transverse score or division lines which folds now intersect the tab, causing the tab to lie in the plane of the strip but without being weakened or perforated. 1

Referring to the drawing, 1 is the strip of 50 transfer material and 2-2 are tabs or tongues of material cut therefrom at spaced intervals agreeing substantially with the spacing vof the transverse division lines upon which the strip is to be subsequently divided into succeeding sheets.

reversely folded upon the and the strip including the tab is then folded reversely upon succeeding transverse division lines 4, the fold lines of the strip intersecting the tabs 2 upon the fold line 6 thereof. Thus the tab is caused to lie in the plane of the strip beyond the fold lines thereof, but the `tab is maintained of maximum strength throughout. and the fold line of the tab not having been previously weakened, the tab will maintain its position and is not so likely to become displaced or reversed between the strip before reaching the writing position.

The tabbed strips of transfer material l, are assembled in interleaved relation between superposed strips 7-7 of recordmaterial and is shown particularly in Fig. 3 the'superposed strips being collectively folded to and fro coincident with the registering score lines 8 of the record strips and the lines 6 of the transfer strip.

After usel the packets of used sheets are simultaneously detached from the supply strips by grasping the sheets and tearing them transversely upon the registering division lines 8 and 6 of the respectiverecord and transfer strips, after which the detached sheets are easily and quickly separated from each other by collectively grasping the record sheets within the area of the cutouts 5 of the interposed transfer sheet and simultaneously grasping the protruding tabs 2 of such transperforating device or other fer sheets at the opposite margins of the packet -and pulling'the respective sheets in opposite directions as isillustrated in Fig. 6.

As an alternative construction, the scoring rule, means for eiecting `the scoring or delineation of the division lines 4, may be interrupted or cutaway coincident with the position oi' the tabs 2 thereby terminating the division lines at the margins of the cutout 5 50am! leaving the tabs 2 unscored and unweakened.

From the above description it will be apparent that there is thus provideda device of the character .described possessing the particular features of advantage before enumerated as desir- .A able; but which obviously is susceptible of modi- Fig. 2, and the strip 1 is then ti or weakening of the strip upon they ncation in its form, proportions, on` and arrangement of parts detail construcwithout departing'from the principle involved or sacrincing any of its advantages.

While in order to invention has been described in langua orless speciilc as to structural features,y it is to' be understood that the invention isnot limited to the lspecific featin'es shown, but that the means and construction herein disclosed comprise the preferred form oi several modes of putting the invention into effect, and the invention is therefore claimed in any of its 'forms or modiilcations within the legitimate and valid scope of the appended claims. A

Having thus described my invention, I claim: 1. The herein described method of producing tabbed transfer material, including cutting a strip of material to form tabs at spaced intervals. folding' the tabs backwardly upon the strip, transversely scoring the strip of material for subsequent division upon lines -oifset beyond the fold line oi' the 3. The herein described method of producing` manifolding transfer material, including forming in a strip o'f transfer material a'succession ot integral tabs at spaced nintervals, displacing the tabs and providing transverse' division lines on which the strip secting the areas from which the tabs were diseompiy vvwith the statute the is divisible into sheets i nter'A pioeed but in non-intersecting relation with the 4. The herein described method of producing manifolding transfer material, including formfing in the strip a succession spaced intervals, displacing the tabs` therefrom and providing transverse division lines upon the strip in onset relation with the bases of the, tabs whereby the material of the tabs will not be intersected thereby and returning the tabs to substantially original relation with the strip.
